[Débutant] timer dans une form

timer dans une form

Bonjour ,

Je souhaiterais intégrer dans une form, une barre de défilement et un timer.
L'objectif est de définir le temps ou la form est active(a l'issu du temps la form se ferme) ,la barre de défilement permet visualiser l'évolution du temps.

Pouvez-m'aider ?

merci de votre expertise

Bah on comprend pas exactement ce que tu souhaites faire.
Explique nous en details.

Cordialment

    Private Sub frmFermeAuto_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ProgressBar1.Minimum = 0
        ProgressBar1.Maximum = 100 ' 100 fois
        ProgressBar1.Value = 0
        ProgressBar1.Step = 1
        Timer1.Interval = 100 ' 0.1 seconde
        Timer1.Start()
    End Sub
 
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        If ProgressBar1.Value >= 100 Then
            Timer1.Stop()
            Close()
        Else
            ProgressBar1.PerformStep()
        End If
    End Sub

Bonjour,

Exactement ce que je souhaitais, un énorme merci

Bonjour,

alexandre1004, en effet la question n'est pas facilement compréhensible, mais il veut une form (peut-être du style d'une messagebox) qui se ferme toute seule au bout d'un certain temps s'il n'y a eu aucune action de la part de l'utilisateur.

Voici un exemple en C#, je te laisse transposer en VB (car mes vieux souvenirs de VB sont loins, ça me prendrait trop de temps...).
